I have these two equations to solve for a1 and wc, this is what I have tried?
syms a1 wc T1 T2 real
syms c1 d1 e1 f1 g1 h1 k1 l1 m1 n1 real
syms c2 d2 e2 f2 g2 h2 k2 l2 m2 n2 real
my_1 = (c1 + d1*a1)*sin(wc*T1) + (e1 + f1*a1)*cos(wc*T1) + (g1 + h1*a1)*sin(wc*T2) + (k1 + l1*a1)*cos(wc*T2) + m1 + n1*a1
my_2 = (c2 + d2*a1)*sin(wc*T1) + (e2 + f2*a1)*cos(wc*T1) + (g2 + h2*a1)*sin(wc*T2) + (k2 + l2*a1)*cos(wc*T2) + m2 + n2*a1
[A,B] = solve(my_1,my_2,a1,wc);

the result means that your system don't have solutions or can't find them. try to assign values to your constants and then solve
